# tug-puller2
Tug of War puller, fine-tuned from Nico-robot/microduck-tug-of-war (via our tug-puller1) by self-play against its own earlier checkpoint with a stronger pull reward. Plain network, no seed tables.
A **perpetual** policy for the [microduck](https://github.com/pollen-robotics/microduck) (61-D observation, 14 actions, 50 Hz). Runs until told otherwise — a gait, loaded into a policy slot.
## Run it on a robot
```bash
sudo robotctl policy load <slot> juicenv/microduck-tug-puller2
```
The observation normalizer is baked into `policy.onnx`; feed raw observations.
`manifest.json` follows schema 2 of the microduck policy manifest (`docs/policy-manifest.md` in the daemon repo).
A remix of [Nico-robot/microduck-tug-of-war](https://huggingface.co/Nico-robot/microduck-tug-of-war).
